To all whom it may concern:

Be it known that we, FRED L. CAIN and CONRAD J. Donrr, citizens of the United States of America, and residents of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Outlet-Box Hangers, of which the following is ism-specification.-

This invention relates to that class of hangershvhich are adapted for attachment between adjacent joists or like parts of building structures for the support of outlet boxes, electroliers and the-like,in a laterally adjustable manner. And the -present improvement has for its object to provide a simple and efiicient structural formation and combination of parts, affording a ready and secure clamping together of the hanger bar and the carrier head, a simple and effective attachment of the outlet box, and a convenient means for the attachment of the tubular electrolier stemof the ordinary standard size, all as will hereinafter more fully appear.

In the accompanying drawing: Figure l,

is a sectional elevation illustrating the gen-- eral arrangement of parts in the present invention. Fig. 2, is a plan view of the same.

Similar reference numerals indicate like parts in both views.

Referring to the drawing, 1 represent portions of two adjacent joists or like members of a building structure, to which the present invention is applied.

2 designates the usual hanger member spanning the space between the joists l, aforesaid, and provided at its respective ends with angle flanges or bends 8, b which the hanger member is attached to said joists by screws or like fastening means.

In the preferred construction shown, the hanger member 2 is formed by two flat metal strips or bars 2 and 2 arranged side by side and capable of adjustment one along the other to suit varying distances between the joists, etc., to which they are to be secured.

4 designates the main or body portion of the carrier head of the present invention. Said bod portion is of a hollow cylindrical form an is formed with a transverse aperture or passage way 5, which receives the aforesaid hanger member 2, as shown.

6 designates an annular collar dis osed at the lower end of the aforesaid main body portion of the carrier head, and preferably formed integraltherewith as shorwn.

7 designates a screw-threaded shank de= pending from the main body ortion be low the annular collar 6, an adapted for the attachment of an electrolier stem. The present construction enables said screwthreaded shank 7, to be made of a much smaller diameter than is required in the main body portion 4, and in consequence the present structure is adapted for the attachmentbf the standard small size electrolier coupling nipples, instead of necessitating the use of large and special sizes of coupling nipples, as heretofore required in the ordinary type of hangers for outlet boxes, etc.

8 designates a clamping screw engaging a centrally disposed screw-threaded orifice in the upper closed or cap portion 9 of the main body a of the carrier head, and adapted to have bearing against the top edge of the hanger member 2, to firmly clamp and bind the carrier head upon the hanger memher at a desired point along the same, and in a ready and convenient manner.

10, designates an outlet box, of an ordinary commercial form, provided with the usual central opening in its upper head adapted to encompass the main body 4 oi.

' the carrier head, and rest and have abutment upon the annular collar 6, against which it is held by the hanger member 2, under the stress of the clamping screw 8, aforesaid.

In an initial assemblage of parts, the main body 4 of the carrier head is passed through the central opening of the outlet box 10, with the annular collar 6 abutting against the underside of the head of said outlet box. The fiat metal strips constituting the hanger member 2 are then assed through the transverse aperture 5 ol the carrier head aforesal Having thus fully described our said in-' vention, what we claim as new and desire to secure by Letters Patent, is:

1. The combination of a hanger member adapted for connection to adjacent supports, a carried head having a cylindrical body portion transversely apertured for the reception of said hanger member, a clamping screw fitting a central screw-threaded orifice in the cap portion of said body portion and having bearing upon the top surface of the hanger member, said carrier head having a screw-threaded lower end or shank'and an annular collar intermediate of said shank-- adapted for connection to adjacent supports,

a carrier head having a cylindrical body portion transversely apertured for the reception of said hanger member, a clamping screw fitting a central screw-threaded orifice in the cap portion of said body portion and having bearing upon the top surface of the hanger member, said carrier head having a reduced and screw-threaded depending shank and an annular collar intermediate of said shank and the aforesaid main body portion, and an outlet box supported on said annular collar.

3. The combination of a hanger member formed by a pair of flat strips arranged side by side and adjustable one u on the other, a carrier head having a cylin rical body portion transversely apertured for the reception of the flat strips formin the hanger member, a clamping screw fitting a central screw-threaded orifice in the cap portion of said body portion and having bearing upon or July, 1914.

meaese the top surrace of the aforesaid strips, said carrier head having a screw-threaded lower end or sham and an annular collar intermediate of said shank and 'the aforesaid main body portion, and an outlet box supported on said annular collar.

4. The combination of a hanger member formed by a pair of fiat strips arranged side by side and adjustable one upon the other, a carrier head having a cylindrical body portion transversely apertured for the re ception of the flat strips forming the hanger member, a clamping screw fitting a central screw-threaded orifice in the cap portion of said body portion and having bearing upon the top surface of the aforesaid strips, said carrier head having a reduced and screwthreaded depending shank and an annular collar intermediate of said shank and the aforesaid main body ortion, and an outlet box supported on said annular collar.
